Hyper-Detailed Macro Photography Prompt: Japanese Coin as a Megacity

# Role
You are the world's leading micro-miniature artist and photographer.
You will reinterpret all the surfaces, edges, engravings, scratches, and text of a Japanese coin as urban structures, architecture, and infrastructure.

# Task
Using a real 500-yen coin as the stage, reproduce the engraved number "500" itself as a miniature, gigantic architectural complex, and further utilize the coin's rim (reeded edge) as circular railway infrastructure to generate an ultra-high-definition macro photograph-style image.

# Core Concept
- Use **only the elements originally present** on the coin
- "500" = The skeleton of the city
- Coin rim = The circular railway surrounding the city
- Scratches, steps, shadows = The city's topography

# Logic

## 1. Surface (Base)
- A real 500-yen coin
- Champagne gold metallic luster of nickel brass
- Faithfully reproduce fine scratches from use and steps in the engraving
- Clearly depict the reeded edge (rim)

## 2. Scale
- People, vehicles, and trains are much smaller than the "500" engraved on the coin
- The entire city is precisely arranged along the shape of the "500"

## 3. Integration (Fusion)
- The "5", "0", and "0" are gigantic numeral-shaped megastructures carved from metal
- The edges and contours of the numbers become roads, sidewalks, and rooftop terraces
- The coin's rim functions as a **circular elevated railway** that circles the city

# Scene
An ultra-high-density city reminiscent of the Shibuya Scramble Crossing.
The "500" text forms the central structure of the city, and micro trains run along the coin's rim, surrounding it.

# Architectural & Infrastructure Details

## The "500" Text City
- **5**
  - Curved section: Mixed-use commercial facilities, digital billboards
  - Vertical line section: Ultra-high-rise office buildings
- **0**
  - Ring-shaped hollow building
  - Interior is a plaza or scramble crossing
  - Pedestrian crossings and crowds are densely packed

## Coin Rim (Circular Railway)
- Each reeded notch appears like a pillar or sound barrier of an elevated bridge
- Extremely thin rails are laid along the curve of the rim
- Micro commuter trains are running
- Some stations are directly connected to the "5" or "0" architecture

# Additional Details
- The shadow of the real "500" engraving and the shadow of the miniature city overlap
- Scratches on the coin surface function as asphalt cracks or signs of wear
- Train lights reflect on the metal surface, illuminating the city
